Abstract

A tolerance ring (152) is provided to axially support a first member, such as an actuator cartridge bearing assembly (112), about a second member, such as a post (132). The tolerance ring is configured to have increased hoop strength to resist deformation during handling and installation. The tolerance ring has a substantially cylindrical base portion (148) from which a plurality of spaced apart contact portions, or corrugations (146) extend. A brace portion (154, 164) circumferentially extends from the base portion to increase the hoop strength of the tolerance ring.
